Whether they're starting a new school or new grade, each child's advised to hold onto the glitter or sprinkle it somewhere important, such as their backpack or bed pillow, to help ease their anxiety about the impending transition.

Peggy is starting school this week and has just received a letter from her teacher with a bag of 'jitter glitter' to put under her pillow to help with any nerves she might have. I can't get over how thoughtful this is 😍 pic.twitter.com/bOeO1AtiMd

"As someone who campaigns for mental health awareness, I felt incredibly reassured that Peggy was going to be in the care of someone who would be mindful of her emotional needs," Hardy told Babble.

"I think normalizing conversations surrounding not feeling okay and making room for communication rather than urging [kids] to pop on a brave face is incredibly important," she added.

But, when it came to assuaging Peggy's fears, her new teacher's gift truly did the trick. As Hardy told CaféMom, Peggy's bravery was on full display as she embarked upon the first day of her school career. In fact, she's already wise beyond her years, as she decided to ration her glitter in case of future emergencies.

"Peggy wouldn't let us use it all because she wanted to save some in case she gets the jitters again."

With all that glitter in reserve, it's safe to say Peggy will never let anyone dull her sparkle.
